Understanding the Dangers and Treatments for Hypotension

Understanding Low Blood Pressure

Blood pressure is the force of blood pushing against the walls of arteries. It is recorded as two numbers—systolic pressure (as the heart beats) over diastolic pressure (as the heart relaxes between beats). Normal blood pressure ranges are typically considered around 120/80 mm Hg.

However, some people naturally have lower than average blood pressure readings. This condition is known as hypotension or low blood pressure. While not always a cause for concern, low blood pressure can lead to troublesome signs and symptoms in some cases.

What Causes Low Blood Pressure?

There are a variety of potential causes behind chronically low blood pressure readings, including:

• Genetics
• Pregnancy
• Endocrine problems
• Nutritional deficiencies
• Dehydration
• Heart conditions
• Medications

In other instances, low blood pressure arises suddenly due to a specific event or trigger like standing up quickly, being in excessive heat, or experiencing trauma or blood loss. This is referred to as orthostatic or postural hypotension.

Risk Factors for Hypotension

While hypotension can happen to anyone temporarily, certain individuals are more prone to persistently low blood pressure readings, including:

• Women, especially pregnant women
• Young adults under age 50
• People over age 65
• People with low BMI
• People with heart conditions
• People taking certain medications

Is My Blood Pressure Too Low?

Despite averages for normal blood pressure, there is no universal threshold that defines blood pressure as definitively too low. Some people may function fine at lower pressures without symptoms or health consequences. Those with chronic hypotension often have well-adapted bodies.

Still, seeing your doctor can help determine if your blood pressure is at a risky level based on your medical history, medications, lifestyle factors, and evaluation of your symptoms.

Levels of Low Blood Pressure

As a general reference, levels of hypotension include:

• Normal: Less than 120/80 mm Hg
• Prehypertension: 120–139/80–89 mm Hg
• Stage 1 Hypertension: 140–159/90–99 mm Hg
• Stage 2 Hypertension: 160 and higher/100 and higher
• Hypotension: Less than 90/60 mm Hg
• Severely low blood pressure: Systolic below 80; diastolic below 50

Pay Attention to Symptoms

Rather than relying on numbers alone, listening to your body's symptoms provides important clues about whether your blood pressure may be dangerously low, such as if you experience:

• Fainting or dizziness upon standing
• Blurred vision
• Nausea
• Fatigue and weakness
• Very rapid, shallow breathing
• Irregular heartbeat

Dangers and Complications

In many cases, individuals with low blood pressure experience minimal symptoms and risks. However in some instances, it can contribute to concerning short- and long-term health effects.

Effects on Daily Life

For those more impacted day-to-day, low blood pressure may interfere with quality of life by causing issues like:

• Inability to exercise or be active
• Frequent fatigue and weakness
• Difficulty concentrating; mental fog
• Lightheadedness with position changes
• Increased fall risk

Potential Medical Complications

Over time, the vascular effects of hypotension can also lead to problematic complications such as:

• Heart damage or failure
• Dangerously low blood flow
• Electrolyte imbalances
• Poor organ function
• Stroke risk

Treatment for Low Blood Pressure

The course of treatment depends greatly on the cause and severity of low blood pressure.

Lifestyle Changes

For mild hypotension, simple home treatment approaches may help boost blood pressure levels to safer ranges. These include:

• Increasing fluid and salt intake
• Wearing compression stockings
• Elevating head while sleeping
• Moving slowly when changing positions
• Engaging muscles before standing

Medical Interventions

If self-care strategies are ineffective and symptoms persist, a doctor may recommend further medical interventions such as:

• Discontinuing blood pressure medications
• Changing dosages of medications
• Prescribing corticosteroids or hormone therapy
• Surgery to normalize blood pressure

In acute situations with severe drops in blood pressure, immediate medical attention is vital.

Living with Low Blood Pressure

Adapting day-to-day routines can help those with frequent low blood pressure readings live well.

Monitor for Symptoms

Keep alert for signs your blood pressure may be falling to problematic levels, like fatigue upon standing or exercise intolerance. Tracking symptoms and detailing them for your doctor can help guide management.

Make Diet and Lifestyle Changes

Boosting fluid and salt intake, wearing compression garments, and slowly changing positions can help stabilize blood pressure. Gentle exercise may also help avoid deconditioning.

Use Caution with Certain Medications

Work closely with your doctor to continually evaluate medications that may contribute to drops in blood pressure, such as diuretics, beta blockers, and antidepressants.

Seek Support If Needed

Those experiencing depression, isolation, or disability related to quality of life effects of low blood pressure should reach out for professional or community support services.
